CLOSURE OPERATING MEANS Filed Sept. 22. 193C:y

Bymanzm llomey lPatented Mar. s, 1932 UNITED* STATES PATENT oFFlcl-z'l J'SEIEH FANTACI, 0F ROCHESTERQ NEW YORK CLOSURE OPERATING MEANS Application mea september 22, 1930. v serial No. 483,696. v

The primary object, of the inventionis to Y generally improve upon prior art closure operators by providingi'astructurewhich is quite simple, positive in action, and susceptilble of better fullilli-ngthe requirements of an invention of this general classification.V

- Other structural 'featuresand advantages will become more readilyapparent from the stress ofthe links 16 and 18 on the propfollowing description and drawings.

In the drawings: Y .e Figure 1 is an inside view of la garage show ing the general assembly of part-s. l

Figure 2 is a ho-rizontal section on the line22 ofFigureZV f In the drawings, the garage doors are distinguished by the numerals 8 and 9 respectively. These are Vof the-usual horizontal v swinging type and mounted on hinges 10.

The numerals 11 and 12designate supporting brackets attached to the-ceiling within the vicinity ofthe doors. l'

Pivotally supported from the bracket 11 is a bell crank 13, and'supported from the remaining bracket 12 is a similar bell crank 14. There is a slight difference in these bell cranks when they are supported in reversed relationship. The bell crank 13 has its short arm at approximately an acute angle with the long arm. The short arm of the bell crank 13 is at an obtuse vangle to thelong arm and these bell cranks are connected to-V f gether, through the medium of a tie rod 15 so that they are simultaneously actuated. The numeral 16 designates a push pull link connected to the long arm of the bell crank 13 and also pivotally connected to a bracket 17 on the upper central portion'of the-door- 8. The numeral 18 designates a similar push pull link pivotally connected to the bell crank 14 and pivotally connected at its opposite end to a bracket-19 on the door 9. When the doors areclosed, the links 16 and 18 occupy the position shown, the link 18 intersecting the jointbetween the rod 15 and the short of the handle 20, the doors can be closed from the open dotted line positionin Figure 2, to j s l arm of the bell crank 14C. By catching hold l.

occupy the full line position shown in the Y same lligure. `By releasing 'the .retainingV means and pushing the doors outwardly, it is obvious that the-linkage struct-ure comes into play for moving the doorssimult'aneously or V in unison.

In fact, the system is suchas to preventl binding and toinsure smoothoperation ofk the doors` 8 and V9 when moving either to open or closed position. `This is partially brought about by the centralized outward v erly placed brackets 17 and 19,

Y What isclaimed is:

tively liXed supporting brackets, a bell cranky pivotally mounted in a horizontal plane at a pointintermediate its ends on one bracket and havingV its short larm, directed outwardly whenthe doors are closed, said short armVb-eing at an approximate acute angle with respect to the long arm, a second bell crank pivotally supported in a horizontal plane intermediate its ends on the remaining bracket, the short larm thereof being at an obtuse angle with respect to the adjacent long arm and being directed laterally inf wardly withrespectto the door, a tie rod connecting said short arms together, bracketsattached to the upper cent-ral portions Aof the doors, a pair of-individual push pull links pivotally connected at their outer ends to said'door brackets andpivotally connected at their inner ends to the free end portionsV of the long arms of the aforesaid bell cranks. In'testimony whereof I affix my signature.
